Gane, not to fear, we all started out knowing little to nothing about these sandcast CB750's.
You, as are all members, most welcome. We appreciate, encourage and welcome member volunteerism and participation at any level. We hope you continue to share on the BB.
You have a very early vin sandcast, highly collectable and very valuable.
If you look at the BB topics, you'll see a category titled "88 Distinctions." Early bikes such as yours have over 90 distinctions making them different than later sandcasts. I'd encourage you to study this list.
Would be really great if you could start a category all of your own on this BB like Wayne, (vin 576) and Mark (vin 97.)
As KP mentioned, you'll see their categories near the bottom of the BB. And, as KP suggested, it's highly encouraged new members study thoroughly the website and BB, as there is an immense amount of information to learn many details of these machines.
I would really encourage you to ask Wayne Telford, our BB manager to assist you setting up your own own category on the BB.
Sure hope you can share info and pics about your bike, as we all have so much more to learn and it would really be a help to fellow owners of these early vins.
These early vins do not have production dates on steering neck tag nor casting dates on upper or lower crankcases, unlike later vin sandcasts.
The biggest challenge with these early vins is if the bike is not complete, finding parts will be not be necessarily easy. Certain parts, such as the 19 liter tank which came original on your 114 can be difficult to find and expensive. Be brave !!!!
What is your engine vin ?
